TI中文支持网各位工程师好，本人想把ndk和ipc工程合并，用的是helloworld_evmc6678l和shmIpcBenchmark_c6678l工程，合并步骤如下：
1.将shmIpcBenchmark工程的cfg配置文件拷贝到helloworld.cfg文件下；
2.改写helloworld.c文件，将ipc相关的头文件和函数加入其中；
3.编译可以通过，但是下载到core0.core1后有问题；显示：
[C66xx_0] timerFreq.lo = 1000000000. timerFreq.hi = 0
[C66xx_0] cpuFreq.lo = 1000000000. cpuFreq.hi = 0
[C66xx_0] Core ("CORE0") starting
[C66xx_1] Invalid CIO command (24) in the CIO buffer at address (0x80693380) was not recognized. Please check the device and program memory maps.
[C66xx_1] cpuFreq.lo = 1000000000. cpuFreq.hi = 0
[C66xx_1] Core ("CORE1") starting
发现程序一直停留在语句attachAll(numCores)，无法进入下一语句。请问是怎么回事？望哪位工程师解答一下，谢谢。

eric long：
单步调试时候，发现core0能够运行attachAll(numCores)直到bios_start;但是core1一直跳不出attachAll(numCores)中的如下循环：
if (MultiProc_self() != entry.ownerProcId) { do { status = Ipc_attach(entry.ownerProcId); } while (status < 0); }
status == -11，查了下，-11表示Operation was not ready，那么需要修改什么呢？
